A kind of invention by make the technology excellence band together of vacuum distillation refines and Vacuum and electromagnetism refine. A kind of methods and equipment for fine of Non-ferrous metals, the unusual is: use the electromagnetism force and mix round effect of electro-magnetic induction for heat up and mix round and element distill process under electro-magnetism suspend state of Non-ferrous materials. A kind of equipment and equipment for fine of non-ferrous metals consist of vacuum furnace body, electro-magnetism loop, crucible, condenser and materials vacuum resent device, etc.; The main character is: the electro-magnetism loop is electro-magnetism conductor suspend loop which located the outside or inside the body of the furnace with a tier of insulation and magnetism transmit material. The aim of which is to develop the pureness of the product by electro-magnetism suspend vacuum distillation or deoxidize distillation and efficiency of smelting; reduce the cost of the smelting.
